In people with weak venous valves, gravity forces large quantities of blood back down into distal parts of the vein. This pressure overloads the vein and pushes its wall outward. After repeated overloading, the walls lose their elasticity and become stretched and flabby. Such dilated and tortuous veins, caused by incompetent valves, are called varicose veins. These may be due to heredity, mechanical factors (prolonged standing and pregnancy), or ageing. Because a varicosed wall is not able to exert a firm resistance against the blood, the blood tends to accumulate in the pouched-out area of the vein, causing it to swell and forcing the fluid into the surrounding tissue.
Varicosity of the rectal veins is known as haemorrhoid (piles). It develops when the viens are put under pressure and become engorged with blood. If the pressure continues, the wall of the vein stretches. Such a distended vessel oozes blood, and bleeding or itching are usually the first signs that a pile has developed. Stretching of a vein also favours clot formation, further aggravating the swelling and pain. Initially contained within the anus (first degree) they gradually enlarge until they prolapse or get extended outward on defecation (second degree) and finally remain prolapsed through the anal orifice (third degree). One particular reason of piles is constipation.
